Use the Microsoft Wireless Display Adapter

Here are some things to know before you start using your adapter:

• The adapter works best if you have both an HDMI port and a USB charging port on your HDTV, monitor, or projector.

• This adapter needs to be connected to a USB charging port because it draws power from the USB connection.

• Make sure your Windows PC has the latest updates. For info on checking updates, go to Update Windows.

• Make sure your adapter also has the latest firmware. To learn how to update the firmware, see Update the Microsoft Wireless Display Adapter.
